I preferabl bend this guide member so that it assumes; roughly the shape of a portion of an ellipse when iewed from the side. as indicated in Fig. 2. since this has been found hr experiment to be the shape cans ing the least strain on the yarn. The edges of the guide member are rounded so as not to wear the yarn unduly.

The operation of the device is as foll.)\\': :-'l'he lower end of the yarn on bobbin E. having been lirst tied by the operator to the upper end of the yarn on bobbin 3. as indicated at X. and the tied hortio'n ot' the yarn being placed outside the guide wire 13. the upper end a of the yarn on bobbin 2 is threaded through the tension device, the thread guide. and engaged with the spool. and the spooler set in motion. 'hile the yarn is being drawn off from bobbin 2 the yarn passes over the guide member substan tially as indicated in Fig. l. the iosition of the balloon which the yarn torms during the process of unwinding being roughly indicated at 19, 19. lpon the exhaustion of the yarn on bobbin 2, the tied ends will be drawn upwardly over the outside of the guide until the slack has been taken up and unwindin from bobbin 3 begins. The yarn from be in 3 now 5 over the guide member at substantially the point 18. and thence to the tension device. thread guide and spool. I

By the use of this guide member the train sition of the unwinding operation from the first to the second bobbin is made easily and without a sudden jerk, and breakage of the yarn is thus avoided.

This guide member acts. therefore. as a guide for the yarn during the whole process of unwinding, the yarn being guided into a position substantially in the axis of'each bobbin during the period of unwinding from such bobbin. and being guided from one of these positions to the other during the transition of the unwinding operation from the first to the second bobbin.

The only mechanism which need he sup- )lied to a spooling machine as ordinarily in use for the purpose of adapting it to continuous bobbin feed in accordance with my invention, is this guide member. which is simple and easy to construct.

It will be obvious that many changes might be made from the form shown in the drawings, without departing from the spirit of my invention.

What I claim as new and desire to secure by Letters Patent is 1-- 1. In mechanism of the clas described. a pair of parallel skewers for bobbins mounted placed guiding member operatr-n transition of the unwinding ogwraiiou one bobbin to the other.

(5. In mechanism of the class described. a pair of skewers for bobbins and -a guide member substantially Y-shaped. having its stem in a plane substantially parallel to planes containing the axes of the bobbins, and the outer edges of its arms beyond the free ends of said bobbins and approximately intersecting the axes of the bobbins respee tively.

12. In mechanism of the class described, a pair of skewers for bobbins, a guide member having edges extending to points beyond the free ends of the bobbins and substantially in line with their axes respectively, and continuous therewith a portion extending outwardly from the plane of the axes of the bobbins, then lengthwise of the bobbins, and then inwardly to a point near the base of said bobbins.

13. In mechanism of the class described, a

pair of skewers for bobbins, a guide member having rigid portions for guiding yarn while being unwound from said bobbins, and a resilient extension for gu ding the yarn during the transition of the unwinding process from one bobbin to the other.

14. In mechanism of the class described, a pair of skewers for bobbins, a guide member having rigid portions placed beyond the free ends of said bobbins for guiding yarn while being unwound from said bobbins, and a resilient extension for guiding the yarn dur ing the transition of the unwinding process from one bobbin to the other, the extremity of said resilient extension being between and substantially in line with the bottoms of the two bobbins.

15. In mechanism of the class described. a pair of skewers for bobbins, a guide member having portions for guiding yarn while being unwound from said bobbins. and a por tion for guiding the yarn during the transition of the unwinding process from one bobbin to the other. said guide member having substantially the form of a portion of an ellipse as viewed in side elevation and extending from points beyond the free ends of the bobbins to a point near their bases.

In witness whereof. I have signed my name to this specification.
